The name TIANZHUOJINSHU is a romanized commercial rendering of the Chinese name 天卓五金.

• 天卓 (Tianzhuo) — the specific brand identifier.
• 五金 (wǔjīn) — literally “five metals,” but in modern Chinese commercial usage refers broadly to hardware, metal fittings, tools, and fastening products.

Accordingly, Tianzhuo Hardware is a more natural English interpretation of 天卓五金 than a literal translation of the individual characters. It is important to distinguish TIANZHUOJINSHU from other businesses using the word “Tianzhuo” (天卓). Available marketplace evidence specifically identifies products sold under the TIANZHUOJINSHU name with Tianzhuo Hardware, while corporate and patent records identify Zhongshan Tianzhuo Hardware Technology Co., Ltd. as the related hardware enterprise.1

The company most strongly associated with the brand is Zhongshan Tianzhuo Hardware Technology Co., Ltd. Public business information lists the entity as a Chinese metal products and hardware enterprise located in the Zhongshan Torch Development Zone in Zhongshan, Guangdong Province. Current business listings indicate a registered capital of RMB 6.06 million, a legal representative of Feng Weijian (冯伟坚), and a business scope covering hardware product research and development, hardware manufacturing and wholesale, metal material manufacturing, construction materials, doors and windows, metal tools, metal daily-use products, furniture, and related manufacturing services.

Chinese government records list Zhongshan Tianzhuo Hardware Technology Co., Ltd. among science-and-technology-based small and medium-sized enterprises, and the company appears in Guangdong’s 2019 high-tech enterprise list.

There is some inconsistency in publicly available profiles regarding the company’s founding year. One business profile states that the company was established in 2002, whereas current corporate registration information gives 10 March 2016 as the establishment date. The latter likely refers specifically to the currently registered legal entity; the earlier date may relate to the business’s historical operations or a predecessor organization.

The publicly visible product range of TIANZHUOJINSHU centers on mechanical fastening and general hardware.1

Screws

The brand offers a broad range of machine and fastening screws, including:

• Hex socket screws
• Countersunk screws
• Flat head screws
• Socket head screws
• Set screws and grub screws
• Self-tapping screws
• Security and tamper-resistant screws
• Phillips head screws
• Flanged screws
• Shoulder and specialty screws

Marketplace listings show products manufactured from materials such as 304 stainless steel, 316 stainless steel, carbon steel, alloy steel, and other commonly used fastening materials.1

Bolts, nuts, and washers

Listings for 天卓五金 show numerous combinations of hex bolts, hex nuts, stainless steel nuts, flat washers, spring washers, bolt-and-nut kits, combination fasteners, and high-strength fasteners. The catalog covers multiple strength grades and sizes, including 8.8, 10.9, and 12.9-grade steel fasteners as well as 304 and 316 stainless steel products.

Stainless steel hardware

Stainless steel products form a significant part of the visible TIANZHUOJINSHU catalog. Examples include 201 stainless steel eye bolts, 304 stainless steel screws, 304 stainless steel threaded rods, 304/316 stainless steel bolts, stainless steel expansion bolts, and stainless steel retaining components. The use of 304 and 316 stainless steel positions many of these products for applications where corrosion resistance is critical, such as in marine or outdoor environments.1

Expansion and installation hardware

The brand sells hardware intended for construction, installation, and DIY applications. This includes a range of hollow-wall expansion screws offered in sizes including M4, M5, M6, M8, and M10, marketed for fixing materials such as gypsum board and hollow walls.1

General mechanical hardware

Other identified products include threaded bars, retaining rings, knobs, handles, and various specialized fastening components.1

Based on available catalogs, TIANZHUOJINSHU is characterized as a general-purpose industrial and hardware fastening brand rather than a consumer-facing lifestyle brand. Its product strategy emphasizes:

1. Large SKU variety — extensive diameters, lengths, thread types, and head styles.
2. Multiple material choices — particularly stainless steel and high-strength steel.
3. Standardized metric sizes — products are typically specified using M-series dimensions such as M2, M3, M4, M5, M6, M8, M10, M12, and larger.
4. Industrial and maintenance applications — suitability for machinery, fabrication, construction, furniture, equipment maintenance, and DIY work.
5. Online distribution — prominent visibility through Chinese and Southeast Asian e-commerce marketplaces.

The company associated with Tianzhuo has a specialized background in lock hardware that extends beyond the current TIANZHUOJINSHU marketplace catalog. Patent records identify Zhongshan Tianzhuo Hardware Technology Co., Ltd. as the assignee of multiple inventions and utility models concerning locks and lock cylinders. For example, the company was the assignee of a 2018 patent for a lock cylinder and a 2021 utility model concerning a connectable lock cylinder.

A lock cylinder patent originally associated with inventor Feng Weijian was transferred to Zhongshan Tianzhuo Hardware Technology Co., Ltd. in 2017, providing evidence of the company’s involvement in lock cylinder technology. More recently, a 2025 patent application attributed to the company concerned a clutch mechanism and electronic lock, indicating continued development in locking and electromechanical hardware. This suggests that the company’s technical background encompasses both precision lock hardware and the broader fastening and metal hardware market.

TIANZHUOJINSHU products can be broadly categorized by application:

The exact suitability of an individual product depends on its material, strength grade, dimensions, surface treatment, and specific application requirements.

TIANZHUOJINSHU maintains a visible presence in cross-border e-commerce, particularly on Southeast Asian marketplaces frequented by Philippine buyers. Listings on platforms such as Lazada identify products explicitly as “TIANZHUOJINSHU” and associate them with a Tianzhuo Hardware Flagship Store. Products listed include stainless steel screws, security screws, threaded rods, expansion screws, and other mechanical hardware.1

The brand is also visible on Philippine and Malaysian marketplace listings, indicating distribution beyond mainland China. Chinese e-commerce evidence is considerably broader, with JD.com search results showing 天卓五金 products across thousands of listings, including stainless steel nails, expansion bolts, screws, washers, high-strength socket screws, and other industrial fasteners.

Product descriptions frequently specify material grades and mechanical grades rather than relying on consumer-oriented marketing claims. Common specifications include 304 stainless steel, 316/316L stainless steel, 201 stainless steel, 8.8-grade steel, 10.9-grade steel, and 12.9-grade steel. These specifications are significant because fastener performance depends heavily on material, strength class, thread dimensions, and manufacturing tolerances. Listings should therefore be evaluated based on the specifications of the individual product rather than assuming uniform performance characteristics across all TIANZHUOJINSHU items.

A notable characteristic of the company behind Tianzhuo is its patent activity. Documented patents include technologies involving lock cylinders, lock-cylinder/key matching systems, connectable lock cylinders, electronic lock mechanisms, and clutch mechanisms for electronic locks. For example, CN213539993U, published in 2021, describes a connectable lock cylinder assigned to Zhongshan Tianzhuo Hardware Technology Co., Ltd.

The company was included in Guangdong’s 2019 list of high-tech enterprises with certificate number GR201944008953.

TIANZHUOJINSHU occupies a value-oriented industrial hardware position, offering a broad assortment of standardized fasteners rather than a narrow premium specialty line. Its primary characteristics include a wide selection of fastener types, extensive size availability, stainless steel options, high-strength fasteners, assorted hardware kits, and applicability to both industrial and DIY tasks. Because much of the brand’s international presence is marketplace-based, consumers in the Philippines typically encounter the name on individual product pages rather than through a standalone corporate website.

Evidence supports the following identification: TIANZHUOJINSHU → 天卓五金 → Tianzhuo Hardware → associated with Zhongshan Tianzhuo Hardware Technology Co., Ltd.

The specific English capitalization “TIANZHUOJINSHU” functions primarily as an e-commerce and marketplace brand rendering, while Chinese domestic listings use 天卓五金 as the brand name. There is no public confirmation that “TIANZHUOJINSHU” is the company’s official registered English corporate name.

Available marketplace evidence shows generally positive individual reviews for several TIANZHUOJINSHU products. Some Lazada listings display 5.0/5 ratings, with customers commenting positively on product quality, fit, and shipping.1 However, these represent small samples and should not be interpreted as an independent assessment of the brand’s overall quality. Similarly, Chinese JD listings show substantial review activity for certain 天卓五金 products, including fasteners with dozens or hundreds of reviews.

TIANZHUOJINSHU is best understood as the international marketplace-facing name for Tianzhuo Hardware (天卓五金), a Chinese hardware brand associated with a Zhongshan-based metal products company. Its visible commercial range is dominated by screws, bolts, nuts, washers, threaded rods, expansion hardware, and other fastening components, with a strong emphasis on stainless steel and standardized metric products. At the corporate and technical level, the associated Zhongshan company also has a history of lock cylinder and electronic lock research and development, including multiple patents and recognition as a high-tech enterprise.

Public English-language information regarding the brand remains sparse. Consequently, details such as a definitive founding history of the brand itself, official English corporate name, global revenue, international market share, manufacturing facility count, and official brand history cannot currently be established with the same confidence as the product and corporate information outlined above.

Basic information

If encountered on a screw, bolt, nut, or other metal fastening product, TIANZHUOJINSHU most likely refers to 天卓五金 / Tianzhuo Hardware. The brand’s core identity is Chinese industrial hardware and fastening products, while its associated company possesses a deeper technical history in lock and security hardware.1
